Multiculturalism - one word, "multi" elements. A word that is important part of modern society today and plays a large role in creating a new political framework. We live in a world of great migration that brings with it new modern societies and schools. Such schools are of great importance to make multicultural communities a positive example of the diversity of coexistence. Music is just one of the areas used in multi / intercultural education. Through music from different cultures, peoples and territories, and through different approaches, it contributes to understanding and learning of equal values. Different approaches also include the use of a textbook, whitch is the most well-known source of knowledge used in teaching. In Croatia, learning from the Primary School Curriculum, some of the goals of education are to nurture responsible, tolerant and solidarity individuals who will have a sense of perserving their cultural heritage, but also a sense of respect for the values of other cultures and nations. The extent to whitch this goal is fulfilled in the teaching of music culture, and how multiculturalism is practiced and whether it is carried out at all in the teaching of music culture, is determined by the analysis of singing content in a class of two textbook kits (Alfa i Školska knjiga). The study of singing content in the classroom revealed the presence of multicultural content, as well as multicultural content in relation to minorities in the Republic of Croatia, through the tasks of determining the number of songs belonging to another culture and people present in different cultures and peoples, and determining the original text and title of the songs.
